WorldWhat was behind the Ceuta migrant incident, and did Morocco instigate it?

EU home affairs ministers held an emergency meeting on Tuesday as Spain briefed its partners on last week’s arrivals in Ceuta. Spain said most of the tens of thousands of migrants who reached the North African exclave had since returned to Morocco. The sudden movement across the sea border raised questions about what triggered it. Carla Hobbs, who heads the European Council on Foreign Relations’ Madrid office, argued that such an event could not have occurred without complicity.
